Product Description:

The AKM44E-BKDNCA-00 is a synchronous servo motor manufactured by Kollmorgen for the AKM Synchronous Servo Motors series. It is intended for closed-loop industrial automation where rapid positioning, speed regulation, and compact installation are critical. Operating with a drive controller, the motor converts commanded currents into accurate shaft movement so that packaging stations, electronic assembly lines, and material-handling gantries can follow programmed trajectories while limiting overshoot.

The motor has an 84 mm frame cross-section and a NEMA flange, allowing direct attachment to standardized gearboxes or brackets. Power conductors, encoder lines, and protective earth share a single i-tec Hybrid or SpeedTec Ready Hybrid connector, reducing cabinet wiring and installation time. Output torque is delivered through an open keyway shaft that provides positive mechanical engagement with couplings or pulleys. Position data is generated by the SFD3 feedback system and transmitted over two feedback signal lines. This digital resolver format supports high update rates for responsive servo control loops. Because the motor is supplied without a brake, an external holding device or the drive’s static torque must maintain the axis position when power is removed.

The motor uses a single-turn inductive encoder, which retains absolute position over one revolution without optical discs or batteries. Its physical envelope follows feedback type code Size 10/15/21, ensuring compatibility with standard Kollmorgen cabling. The rotor stack has a length index of 4; its extended core increases continuous torque without changing the mounting face. Electrical characteristics correspond to winding designation E, allowing the drive to apply a voltage-to-current profile suited to moderate bus voltages and high dynamic response.
